Sony Reader folders

[egwest]

Got a question. Whenever I plug in my Sony Reader and use Calibre, and then eject it and unplug it, sub-folder are left behind in the media directory (i.e: Sony Reader Main Memory (1), Sony Reader Main Memory (2) and so on). And the only way I can seem to delete them is to log in as root and delete them from there.
Does anyone have a solution for this. It is more annoying then a serious problem, but I was wondering if there is a fix for it.

Did you ever figure this out?

Calibre has it's own forums (http://www.mobileread.com/forums/forumdisplay.php?f=166), you might want to ask there.
